Try a lot of WD40 penetrating oil on the other ones. Give it time to soak in, they should come right out. Then go to a hardware store with the old screws or bolts and nuts to buy new ones. You should use a piece of wood like a 2x4 to put between the tank and a jack to hold it up. You want to put something in between the jack and tank to reduce the chance of the jack damaging the tank and to spread the pressure to a bigger area. You will have to replace the broken one. Unfortunately I can't see what your doing unless you want to post a picture or something somewhere. Since I can't see what happened and what it looks like I can't tell you how to remove the broken one. Make sure the tank is empty!

Put a rotary wire brush onto your drill and clean off as much rust as you can on the thread that is showing

Soak them in WD40 or better still Plus Gas overnight, wrap cling film around them to keep the area moist

Try tightening them before you try to slacken them if they do tighten up a bit then put some more effort in with the rotary brush and release fluid

If they are not moving go hire or buy a small nut splitter

Going to put a new fuel pump on a 1992 buick road master cant get the gas out of tank so we can drop it


The fuel line fittings and the tank straps are probably rusted at the threaded bolt and nut. Have some penetrating oil spray onto them and let it sit over night. Use an impact wrench to remove the two nuts. Next remove the fuel lines and drop the tank out. Having an empty tank is good also to lighten the weight

Replacing a fuel pump on a 2002 saturn lw300


You can check in the trunk and remove the felt cover see if there is a round panel cover that you can remove to get to the tank. If your unlucky and have to remove the tank you will have to remove the tank. The cover may be under the spare tire so pull it out. It is not to difficult to do, if you drive it till the gas is almost out you can remove the two bolts that hold the tank in place. Use wd-40 to spray on the bolts and also spray the hinges on the oppitse side of the straps. once the nuts are off drop the tank down. You will need to pull the screws off the tank filling tube so it will come down as well. drop the tank down far enough for you to get to the fuel tank sending unit. it will have philips screws holding it in place. Mark two spots with a felt tip pin, (Sharpe) white is better and mark two holes so you can line the it back up for the holes and the hoses. disconnect the fuel line and return line disconnect the battery of the car for safety then pull the wires off it can be a plug or it may have nuts on them. When you remove the nuts or screws out pull the pump out and you will have to angle the pump to get the float out. I recommend that you replace the pump and the sock on the end of the pump. Do not buy after market buy factory replacement only you only want to do this once. mark the new pump holes on the pump using the old pump as an example, will save a lot of time to get it to fit in and match and the lines will line up, tighten all screws up put the lines back on and the clamps and reinstall the tank in place. yo can use your knees to hold it in place till you get the clamps lined up and started. Screw the nuts down till tight and your set to go just hook up the battery again and your set to go.
SIde Note, Never let your car get below 1/4 of tank of fuel, the reason is gas is the coolant for the pump if it goes lower than that the pump will heat up and will burn out. Many people don't know this so I thought I would add this to your knowledge

Put back on a in tank fuel pump of a 1991 chevy s10 blazer


The rubber ring goes between the tank and the pump/sending unit flange. There should be a nothc on the tank and a corresponding tab on the flange of the pump unit, to ensure correct orientation. Set the lock ring over the flange, and tap in clockwise with a NON_SPARKING drift. The ring will cam lock into place.

I would check the basic things first. Battery Terminals, the Battery itself, gas in the tank, then the probable cause a faulty fuel pump. A quick check of this is to take the air horn t-nut off the 3 inch t handle screw which holds it and spray starting fluid in the throttle body. Do not open the throttle body like an old careburator just spray it in their, put the air horn back on and if it starts it's a probable fuel pump. You can also try to turn on the key three times but do not start it those three times just see if the fuel pump sounds like it's working. On the third try turn the key fully on and if it starts it's a probable fuel pump. If so Google under 100 dot com and they have blazer fuel pumps for 60 or 70 dollars. A fuel pump from an auto parts store will cost you from 250 to 300 dollars. I wish you the best of luck becuase I have replaced four fuel pumps in my own blazer. Good Luck!!!
